g LAST.

Specification of Letters Patent.

Patented Feb. 26, 1907.

T0 all whom it may concern.:

Be it known that I, REUBEN W. PERRY, a citizen of the United States, residing at Stoneham, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Lasts, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My invention relates to hinged lasts, and consists of an externally-operable locking mechanism for retaining the parts preferably automatically locked in lengthened position.

I provide in connection with suitable hinging members a spring-impelled locking member which projects outwardly sufliciently to be operated from the outside of the last.

rI'he constructional details of my invention will be apparent from the following description, taken in connection with the accompanying drawings.

In the drawings, Figure l is a view in side elevation of a last containing my invention. Fig. 2 is a top plan view thereof. Eig. 3 is a transverse sectional view looking at the rear end of the fore part of the last, and Fig. 4 is a view, partly in section and partly in side elevation, of the locking means and hinging device dismembered.

The fore part a and heel part b'may be of any usual or preferred contour and hingin,j connection, being herr-in shown as cut away at .ff b and joined by two pairs of similar voverlapping hinge-plates c c, held in Bxed position in the respective parts of the last by rivetsl 2 3 4 and connected by a transverse pintle 5 passing through alining holes e2 c3. Above the pintle the hinge-plates are cut away, as shown at c4 c5, and provided with overhanging portions cG c7 in position to engage the projecting ends d a" of a cross-bar d2, fast in the locking device, which comprises, besides said cross-bar d2, a tubular member d, extending upwardly, as clearly shown in Figs. l, 3, and 4, and being cut away at d5 to provide a bifurcated lower end adapted to straddle the pintle 5 between the opposite pairs of hinge-plates. Between the pintle 5 and the bar d2 I provide a spring d for automatically raising the locking member into locking position.

The cut-away portions c4 c5 of the hingeplate have a straight upper portion, so as simply to receive the'cross-bar d2 when the last is in lengthened position and permit no play or movement of the parts, as shown in Eig. l but at the lower part of said cut-away portion I provide an oiiset or lateral recess cs, so that when the operator depresses the upwardly-projecting part or handle d3 of the locking device the cross-bar d2 will be in line with said lateral offsets or recesses cs, thereby permitting the heel part to turn up on the fore part.

Having describedmy invention, what I claim as new, and desire to secure by Letters Patent, is

1. A hinged last, having its fore part and heel part connected by a hinge, rovided with overlapping parts at one side o the pintle, the hinge being cut away to form a radial opening between said overlapping parts and the pintle and provided with a lateral recess adjacent the pintle, combined with a locking device extending externally ofthe last for external operation, and having a cross-bar located in said cut-away portion and adapted to enter said recess.

2. A hinged last, having its fore part and heel part connected by a hinge, provided with overlapping parts at one side of the pintle, the hinge being cut away to form a radial opening between said overlapping arts and the pintle and provided with a ateral recess adjacent the pintle, combinedy with a locking device extending externally of the last for external operation, and having a cross-bar located in said cut-away portion and adapted to enter said recess, and means for automatically maintaining said device in locking position.

3. A hinged last, having its fore part and heel part connected by a hinge, rovided with overlapping parts at one side o the pintle, the hinge being cut away to form a radial opening between said overlapping parts and thepintle and provided with a lateral recess adjacent the pintle, combined with a locking device externally operable and movably en-v gaging the pintle and said opening,occupy ing the outer portion of said opening when in locking position and said lateral recess when in unlocked position.

4. A hinged last, having its fore part and heel part connected by a hinge, provided with overlapping parts at one side of the pin- IOO tle, the hinge being cut avvay to form a radial when in unlocked position, and a spring for opening between said overlapping parts and normally maintaining said device in its lockthe pintle and provided With a lateral recess ing position. adjacent the pintle, combined with a locking In testimony `vvhereof l have signed my 5 device having an operating portion extendname to this specification in the presence of I5 ing externally of the last for external operatwo subscribing Witnesses. y tion, and having an inner portion movably l u REUBEN W.
